Hi Briony,
Thank you for your purchase.

Sorry but I did not quite understand what the issue is here. Can you please describe me more, so I can give you my suggestion.

Best regards.

Hello Briony

I'll take over Bogdan's ticket.

There could be a conflict with another plugin or the theme you have active on your website.

Can you please change the theme and see if the issue is resolved? If not, then please deactivate all other plugins except for wpDataTables, refresh the page where the issue is, and see if it is resolved (it should be). If it is, then start activating other plugins one by one, and after each activation refresh the page to see if the issue reoccurred. Once it does reoccur, you will have found the plugin causing the issue.

If the issue is still present I'll need to remote in and take a look.

Please provide me a temporary WP-admin login for your site where this happens, so we could log in and take a look ‘from the inside’ as that’s the most efficient way to see and resolve the issue. We do not interfere with any data or anything else except for the plugin (in case that’s a production version of the site), and of course we do not provide login data to third party. 

You can write credentials here just check Private Reply so nobody can see them except us.

Hi again Briony

Thank you for the credentials.

However, I see WooCommerce hasn't been enabled as a payment option in Amelia:

Also, I don't see the "Appointment" product in WooCommerce, which indicates that WooCommerce wasn't activated yet in Amelia (or that it was deleted). When WooCommerce is activated as a payment option, this product is created, but you're able to choose other products and link them with Amelia. If you wish to do that, that product should be removed from your website's listing, so it can't be bought outside of Amelia, to avoid confusion.

You don't have any services created:

Only events. But they are not connected to WooCommerce. Did you change the settings?
